.To all whom it may concer'n:

Beit known. that-I, GEORGE O. HAWKE, 'a citizen of the United States, residing at Greeniield, in the county of Hancock and' State of Indiana, have invented lew and useful Improvements in Toy Motor-Vehicles, of which the following is a specification.

lThis invention relates totoy motor-vehiu amusing, one in which the air-compressing member or pump constitutes a xture upon the tank, thus permitting ready replenishing of the latter, one wherem the supply-of air Vfor driving the motor may be readily controlled, one in which power will -be positively and directly transmitted from the motorto the vehicle-wheels, and one wherein the. steering-lever may be xed in adjusted position for properly guiding `the vehicle in its'- travel. f

A. further object of thefinvention is tol provideadevice of this character wherein-the vehicle willv be positively driven when turning in either direction and one wherein aconstant pressure will be maintained on the air fed from thestorage vessel to the motor.

With these and other objects in view the invention comprises the novel features of construction andcombination of parts more .e fully hereinafter described.

vention Fig. 2 is a' vertical In'the accompanying drawings," Figure 1 is a side elevation of a toy embodying 4the inongitudinal section centrally through thesame, 4

, Referring'to the drawings, 1 designates the vehicle,.equipped with an air tank or resersus' Vthe lever 7 against rotation is a clampingmember or nut 11.

Sustained upon the top of the tank 2is an en e-cylinder 12, having an air-chest or. ga ve-chaniber 131connectedi with the tank?i ymeanso asu pypipeor uct 14 e uippe .'.With a controlhgig-valve15., therebging arwheel '42 for permittin ranged for reciprocation in the cylinder 12, which communicates with the chest 13 through the medium of ports or passages.

V16 17, a piston 18, the rod 19 of which is connected by a pitman-link 20 with a crank-arm 21, fixed on lthe engine-shaft 22, onwhich is also fixed. a fly-wheel 23 and abelt-pulley 24,

vwhile arranged in the chest 13 is a slide-valve 25, the stem 26 of whichis pivoted to an oper-- ating-lever 27, in turn pivoted to the top of the tank and lconnected by an arm 28 and strap 29 with an eccentric 30-on the\shaft 22.

Fixed to the top of the tank 2 is a bracketarm 31, carrying a stub-shaft 32, on which is journaled a belt-pulley 33, connected with the ulley 24lby means of a belt 34, there being fixed forrotation with the .pulley33 a secondpulley 35, connected, by means of a belt- 36,l with the pulle 8, whereby the drive shaft or axle 3 wil be driven from the engine-shaft 22 during operation `of the engine, as will be readily understood.

Extending rearwardly from the tank 2 is a bracket 37, .to which lis fixed a pump-cylined a pipe or, duct 39, which enters the tank at .-a pomt adjacent the top of the' latter, there being arranged in said cylinder an air-compressing member or pump 40, carried by a rod 41, equipped at its outer end with a handconvenient operation of the ump to supp y air under pressure to the ta ranged a compressing member or iston 43,

acted upon by a spring 44, dispose between the bottom of thev tan 2 and the piston and 2, in which latter there isar-.

engaged at its ends with suitable bearinglugs 45, provided on said parts, it being noted 1n this Aconnection that as the air is pumped into the tank 2 the piston43 is moved downward against the action of spring 44, which is thereby compressed. 1

, The Wheels 9 ard engaged'with the axle 3 by means of a pa l-and-ratchet connection 46 of usual form to permit freeforward rotation of the shaft independently of the wheels,

whereby positive operation of' the vehicle when turning in either direction is insured.

In, practice supposing the tank to be filled with air or other iid underpressure and the parts of the motor to be in the positions illustrated Fig. 2, the Huid will when valve 15 is opened enter valve-chest 13, from whichit will pass through the port 16 vinto c` linder 12 and move the piston 18 forwardly, W e at the same time the valve 25 will move rearwardly IOO 8o Ader 38, to the lowerend of whichis connectfor closing the port 16 and admittin a charge y of air through port 17 for driving t e piston rearwardly, as is usual, itY being understood that throughout the operation lof the motor the air is Valternately admittedthrough the passages 16 17 to opposite sides of the pistonand is exhausted in the usual manner through the valve 25 and port 43. During operation of the piston the shaft 22 will be driven and will transmit power through the medium of the belts 32 36 and their pulleys to the drivewheels 9 for propelling the vehicle, which may be steered by means of the lever 7 ,-it being apparent that after the latter has been properly set to guide .the/vehicle it may be' As the air is A fixed by means of the nut 11. drawn from the tank 2 for operating theA engine the piston 43 moves upward under the action of spring 44, thus maintaining a uniform pressure on the ,air remaining in the tank. It is to be particularly observed that l the. valve 15 serves :noft only for 'starting or stopping the motor, and consequently the vehicle, but may be also employed for regu-l latin the su ply of air to the engine to control t e Spee of the vehicle. Further, it will be noted that owing to the pump being ixed upon the vehicle itmay be readily. manipulated for replenishing the supply of air within the tank 2 when circumstances require.

From the'foregoing it is-apparent that I produce a comparatively sim le inexpensive device admirably adapted orl the attainment ofthe ends in-view, ity bein stood that in attaining these en sminor changes in thedetails herein set forth may be resorted to without departing from the spiritof the invention.A A

Having thus described my invention, what I' claim is- I Y In a device of the class described, a vehicle having `a drive-shaft provided with ground- Wheels, a compressed-air reservoir carried by the vehicle, a motor including a cylinder connected for communication with the reservoir, a piston arranged in the cylinder foroperation by the compressed air, said 'piston'being operatively connected with the 'drive-shaft,

an air-compressor carried by thevehicleand connected withA and for supplying air to reservoir, and a spring-operated pistou movably mounted in 'the reservoir for'maintaining pressureon the air therein.-
